Summary: | A laboratory simulation method is proposed for energy release processes occurring in a fragment of the flare current sheet on the Sun. The method relies on the assumption that the spatial scale of such processes is represented by the current sheet's thickness, whose values can be close for both the solar and laboratory conditions. It is shown that, in an extended current sheet, current dissipation on anomalous resistivity, which ensures the specific power of energy release close to that observed in a flare, is the main energy release mechanism. A rapid compression of the sheet by external magnetic fields can provide the condition for switching on a powerful energy release. The tearing instability developing in a homogeneous neutral sheet leads to the formation of magnetic islands in which the energy release is localized. |
